Centralized power management of wireless devices

ABSTRACT

Systems and methods for centralized power management of wireless user devices are disclosed. In embodiments, a method comprises: monitoring, by a computing device, battery charge levels for remote user devices; identifying, by the computing device, that a battery charge level of a first user device of the remote user devices is below a predetermined threshold value based on the monitoring; identifying, by the computing device, at least one in-use device from the remote user devices based on real-time data indicating that the at least one in-use device is in use by a user; and sending, by the computing device, an alert to the at least one in-use device based on the identifying the at least one in-use device, wherein the alert includes information about the first user device and information regarding the battery charge level of the first device.

BACKGROUND

The present invention relates generally to battery management and, more particularly, to centralized power management of a plurality of wireless devices.

The use of battery powered mobile user devices, including Internet of Things (IOTs) devices, is on the rise. The battery life of a user device and a user's ability to monitor the battery life are important considerations to consumers. Presently, individual user devices may include dedicated software that monitors the battery life and enables users to view the battery charge level for the device. Additionally, secondary user devices (e.g., accessories such as headphones, smartwatches, etc.) may come with dedicated software that can be loaded into a smartphone or the like to enable a user to monitor the accessory from the smartphone.

Disadvantages of such systems include the need for operating system (OS) dependent battery monitoring software (i.e., apps are tailor made for specific OS), which may result in inoperability of battery monitoring software with user devices. Further such systems typically utilize smartphone-specific battery monitoring apps, which are not accessible if the smartphone is off or otherwise unavailable to a user. Further, such systems enable only a single point of contact for a user. For example, a smartphone becomes the only point of contact for obtaining battery updates for other user devices. Moreover, such battery monitoring systems may be based on passive monitoring that enables alerts only and does not allow a user to remotely change battery settings to increase battery life of a user device. Additionally, battery management applications for smartphones are typically device-specific, such that a user having a plurality of user devices of different makes/models may need to load multiple battery management applications onto their smartphone in order to obtain battery charge status updates for all of the devices, which is inconvenient to a user and eats up smartphone resources. Moreover, user device batteries may lose power even while the device is off, and the last battery alert from typical battery management software may not accurately reflect the current state of the device's battery charge.

SUMMARY

In an aspect of the invention, a method includes: monitoring, by a computing device, battery charge levels for remote user devices; identifying, by the computing device, that a battery charge level of a first user device of the remote user devices is below a predetermined threshold value based on the monitoring; identifying, by the computing device, at least one in-use device from the remote user devices based on real-time data indicating that the at least one in-use device is in use by a user; and sending, by the computing device, an alert to the at least one in-use device based on the identifying the at least one in-use device, where the alert includes information about the first user device and information regarding the battery charge level of the first device. Advantageously, methods of the invention enable monitoring alerts to be dispersed to devices currently in use by the user, rather than sending alerts to only one predetermined user device.

In embodiments, the method further includes determining, by the computing device, whether each of the remote user devices includes battery management software. In embodiments, the computing device determines that one or more of the remote user devices does not include the battery management software, and the method further comprises: generating, by the computing device, battery charging data for each of the one or more remote user devices by testing batteries of each of the one or more remote user devices; monitoring, by the computing device, changes in the battery charging data over time; and sending, by the computing device, a notification regarding battery performance to the at least one in-use device based on the monitoring. Thus, methods of the invention advantageously enable battery performance monitoring in user devices without their own dedicated battery management software.

In an aspect of the invention, a method includes: determining, by a computing device, that a remote user device is in an off-line state where battery status data of the remote user device is unavailable to the computing device; initiating, by the computing device, a change in the remote user device from the off-line state to an on-line state where the battery status data is available to the computing device, where the initiating is based on a predetermined wake-up schedule defining a time period between scheduled wake-up sessions; receiving from the remote user device, by the computing device, battery status data of the remote user device; and sending, by the computing device, instructions to the remote user device to revert to the off-line state from the on-line state; determining, by the computing device, a change in battery status by comparing the battery status data to historic battery status data; and determining, by the computing device, whether the predetermined wake-up schedule is to be adjusted based on the change in battery status. Thus, embodiments of the invention enable adjustment of wake-up schedules for improved battery monitoring of user devices.

In aspects, the computing device determines that the change in battery status is less than a predetermined threshold value and adjusts the wake-up schedule by increasing the time period between scheduled wake-up sessions. In aspects, the computing device determines that the change in battery status is greater than a predetermined threshold value and adjusts the wake-up schedule by decreasing the time period between scheduled wake-up sessions. Thus, aspects of the invention enable wake-up sessions to be moved farther apart such that unnecessary draining of the user device battery due to monitoring activity may be avoided. Conversely, aspects of the invention enable wake-up sessions to be moved closer together to adjust for deteriorating battery performance (e.g., ability to hold a charge), over time.

In another aspect of the invention, there is a computer program product comprising a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computing device to cause the computing device to: monitor battery charge levels for remote user devices; identify that a first user device of the remote user devices is a lower battery device when a battery charge level of the first user device is below a predetermined threshold value based on the monitoring; identify at least one in-use device from the remote user devices based on real-time data indicating that the at least one in-use device is in use by a user; and send an alert to the at least one in-use device including information about the battery charge level of the low battery device. Advantageously, computer program products of the invention enable monitoring alerts to be dispersed to devices currently in use by the user based on real-time data, rather than sending alerts to only one predetermined user device.

In embodiments, the computer program product includes program instructions to further cause the computing device to determine whether each of the remote user devices includes battery management software. In aspects, the computer program product determines that one or more of the remote user devices does not include the battery management software, and the program instructions further cause the computing device to: generate baseline battery charging data for each of the one or more remote user devices by testing batteries of each of the one or more remote user devices; monitor changes in the baseline battery charging data over time; and send a notification to the at least one in-use device based on the monitoring. Thus, computer program products of the invention enable battery performance monitoring in user devices without their own dedicated battery management software.

In another aspect of the invention, there is a system comprising: a processor, a computer readable memory and a computer readable storage medium associated with a computing device; program instructions to monitor battery charge levels for remote user devices; program instructions to identify that a battery charge level of a first user device of the remote user devices is below a predetermined threshold value based on the monitoring; program instructions to identify at least one in-use device from the remote user devices based on real-time data indicating that the at least one in-use device is in use by a user; and program instructions to send an alert to the at least one in-use device based on the identifying the at least one in-use device, where the alert includes information about the first user device and information regarding the battery charge level of the first device, where the program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory. Thus, systems of the invention enable monitoring alerts to be dispersed to devices currently in use by the user, rather than sending alerts to only one predetermined user device.

In embodiments, the system includes program instructions to send user selectable battery management options to the at least one in-use device; program instructions to receive a selection of one of the user selectable battery management options; and program instructions to send instructions to the first user device to implement a battery management function based on the selection. Thus, embodiments of the invention advantageously enable remote battery management of user devices from a central location.

In another aspect of the invention, there is a system comprising: a processor, a computer readable memory and a computer readable storage medium associated with a computing device; program instructions to determine that a remote user device is in an off-line state where battery status data of the remote user device is unavailable to the computing device; program instructions to initiate a change in the remote user device from the off-line state to an on-line state where the battery status data is available to the computing device, where the initiating is based on a predetermined wake-up schedule defining a time period between scheduled wake-up sessions; program instructions to receive from the remote user device, battery status data of the remote user device; and program instructions to send instructions to the remote user device to revert to the off-line state from the on-line state; program instructions to determine a change in battery status by comparing the battery status data to historic battery status data; and program instructions to adjust the predetermined wake-up schedule based on the determined change in battery status, where when the change in battery status is less than a predetermined threshold value the time period between wake-up sessions is increased and when the change in battery status is more than the predetermined threshold value the time period between wake-up sessions is decreased. Thus, systems of the invention enable adjustment of wake-up schedules for improved battery monitoring of user devices.

In embodiments, the system determines that the change in battery status is less than 10% and adjusts the predetermined wake-up schedule comprises increasing the time period between scheduled wake-up sessions by 20%. In embodiments, the system determines that the change in battery status is greater than 50% and adjusts the predetermined wake-up schedule comprises decreasing the time period between scheduled wake-up sessions by 20%. Thus, aspects of the invention enable wake-up sessions to be moved farther apart such that unnecessary draining of the user device battery due to monitoring activity may be avoided. Conversely, aspects of the invention enable wake-up sessions to be moved closer together to adjust for deteriorating battery performance (e.g., ability to hold a charge), over time.

DETAILED DESCRIPTION

The present invention relates generally to battery management, and, more particularly, to centralized power management of a plurality of wireless devices. In embodiments, a system and method are provided that alert a user if any of a plurality of registered user devices (e.g., Internet of Things (IOT) devices, wearables, cameras, toys, etc.) reach a predetermined battery power level. Unlike typical operating system (OS) dependent battery management systems, embodiments of the invention provide an OS independent solution enabling a user to monitor the battery charge of a user device regardless of the OS associated with the user device. Moreover, solutions of the invention enable monitoring of multiple diverse user devices, and can dynamically determine which user devices to send alerts based on which devices are currently in use. Aspects of the invention further enable remote power management of user devices, such as the ability to shut down or power off a device. Moreover, embodiments of the invention eliminate the need for a user to download multiple device-specific or OS-specific battery management software applications, freeing up user device resources and enabling a user to control all of their devices from a single interface.

Additionally, in embodiments, a system and method for cognitive battery management is provided that utilizes real-time data about the current state of user device batteries to improve battery power management of the devices. In aspects, the cognitive battery management system and method incorporates the monitoring of on-line and/or off-line registered devices, enabling a user to manage the battery power of all of their registered devices, whether in use or not, to maximize their usable life. In embodiments, a system learns about behaviors/characteristics of each user device battery and creates personalized profiles that are used to monitor the battery level of each user device in a unique way. In embodiments, the cognitive battery management system and method is part of a larger battery management/alert system and method, providing battery level alerts to users.

Based on the above, it can be understood that embodiments of the invention advantageously provide technical improvements to the field of battery management and monitoring. In aspects, a system and method provide technical solutions to the technical problems associated with device-specific or OS-specific battery management software, by enabling remote monitoring of a plurality of diverse devices regardless of their make, model or OS. In this way, user devices may be improved by illuminating the need to download multiple battery management software applications onto the device, thereby saving computing resources. Moreover, embodiments of the invention provide technical solutions to the technical problems associated with single point of contact battery monitoring, by enabling smart battery alerts to only those user devices which are being utilized by a consumer. Further, embodiments of the invention provide the technical improvement of enabling remotely initiated battery management functions for various user devices from a plurality of different user devices. Thus, a user is no longer limited to a single user device (e.g., a smartphone) to manage battery life of their wireless devices. Additional technical advantages result from embodiments of the invention that enable customized monitoring and management of multiple user device, regardless of whether they are on-line and off-line.

The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

Still referring to FIG. 2, in implementations, the power management server 60 includes one or more modules having one or more program modules (e.g., program module 42 of FIG. 1) configured to perform one or more of the functions described herein. In embodiments, the power management server 60 includes a communications module 80 configured to enable communication with the user devices of power management environment 50 via the network 55. In aspects, the communications module 80 is configured to obtain user information (e.g., user device registration information) from one or more users (e.g., via an in-use device 62), and save the user information in the user database 81 of the power management server 60. In embodiments, the communications module 80 saves user information on a remote user database (not shown).

In embodiments, the power management server 60 includes a battery monitoring module 82 configured to determine if registered user devices (e.g., devices 62-66 of FIG. 2) include battery management software. In aspects, the battery monitoring module 82 is further configured to test the battery of user devices which do not include their own battery management software in order to monitor battery performance, and provide alerts (e.g., failing battery alerts, etc.) to users based on the monitored battery performance. In embodiments, the battery monitoring module 82 is configured to monitor battery charge levels of registered user devices (e.g., devices 62-66 of FIG. 2), either directly or through existing battery management software on the user devices. In aspects, the battery monitoring module 82 is configured to determine when a battery charge level of a user device is below a threshold value, identify one or more user devices currently in-use by a registered user, and cause a notification module 83 to send a low battery alert to the in-use device (e.g., in-use device 62).

Still referring to FIG. 2, in embodiments, the power management server 60 includes a management module 84 in communication with the notification module 83. In aspects, the notification module 83 is configured to send selectable battery management options to the in-use device (e.g., in-use device 62) enabling a user to select a battery management option, and communicate the selected battery management option to the management module 84. In aspects, the management module 84 is configured to send battery management instructions to a low-battery user device based on the selected battery management options to cause the low-battery user device to implement the instructions and cause a change in the low-battery user device (e.g., power off the user device, put the user device in energy saving mode, etc.). In embodiments, the battery management module 84 is further configured to determine if the instructions where successfully initiated by the low-battery user device and to generate an alert based on the determination (e.g., an alert that the instructions were initiated successfully, an error alert indicating the instructions were not initiated successfully).

In embodiments, the power management server 60 is configured to provide cognitive battery management for one or more of the user devices of FIG. 2. In aspects, the battery monitoring module 82 is configured to: determine that a user device is in an off-line mode (e.g., powered off, in sleep mode, etc.); cause the user device to change to an on-line mode (e.g., powered on, in an active mode, etc.); receive battery status data from the battery system or battery management software of the user device; send instructions to the user device to revert back to the off-line mode; compare battery status data to history battery status data to determine a difference in battery status; and optionally, adjust predetermined wake-up times in a schedule based on the difference in battery status. In embodiments, battery status data obtained by the battery monitoring module 82 includes battery performance data and/or battery charge level data. In aspects, battery status data is saved locally or remotely by the power management server 60. In embodiments, the cognitive battery management functions of the power management server 60 are performed in conjunction with other battery monitoring and testing functions of the power management server 60.

In embodiments, the power management server 60 includes additional or fewer components than those shown in FIG. 2. In embodiments, separate components are integrated into a single computing component or module. Additionally, or alternatively, a single component are implemented as multiple computing components or modules. Likewise, the user devices of FIG. 2 (i.e., user devices 62-66) may include additional or fewer components than those shown in FIG. 2. In embodiments, separate components are integrated into a single computing component or module, or a single component is implemented as multiple computing components or modules for each of the user device of FIG. 2. For example, one or more user devices of FIG. 2 may or may not contain GUIs (e.g., 70) and/or power modules (e.g., power modules 72, 75) with power management software.

FIG. 3 shows a flowchart of a method in accordance with aspects of the invention. Steps of the method of FIG. 3 may be performed in the environment illustrated in FIG. 2, and are described with reference to elements shown in FIG. 2.

At step 300, the power management server 60 receives user registration information for one or more user devices (e.g., user devices 62-66 of FIG. 2). The user registration information may be submitted by a user and/or may be obtained from other sources. In one example, a user provides information regarding the identification (e.g., make/model, identification number, etc.) of their user devices to the power management server 60 and the power management server 60 obtains additional information regarding the user devices from a remote third party through the network 55 (e.g., information regarding the make/model, including whether the make/model includes associated battery management software). In implementations, the power management server 60 saves the user registration information locally (e.g., the user database 81) or remotely (now shown). In aspects, each user registering with the power management server 60 a plurality of user devices (e.g., user devices 62-66 of FIG. 2). In embodiments, the power management server 60 saves a profile for each user device in the user database 81.

At step 301, the power management server 60 determines whether user devices registered at step 300 include associated battery management software. In aspects, the server 60 obtains information regarding the presence or absence of battery management software from the user (e.g., through a dropdown menu during registration). Alternatively, in aspects, the power management server 60 obtains information regarding the battery management software of a user device through a third party source (e.g., application programming interface (API)), or through the use of a look-up table listing attributes of user devices (e.g., attributes of user devices by make/model including the presence/absence of battery management software).

Optionally, at step 302, when the power management server 60 determines that a user device does not include battery management software of its own at step 301, the power management server 60 initiates a battery performance test. In aspects, the battery performance test includes the following substeps.

At substep 302 a, the power management server 60 monitors a battery of a user device (e.g., battery 71 of in-use device 62) to generate baseline battery charging data. In aspects, the baseline battery charging data provides information regarding the time it takes for the battery 71 to charge or discharge. In one example, the power management server 60 determines that a baseline full charge of the battery 71 lasts between 90 and 100 minutes based on average usage. A variety of existing battery testing methods may be utilized in the implementation of substep 302 a. In aspects, the battery monitoring module 82 of the power management server 60 implements substep 302 a.

At substep 302 b, the power management server 60 monitors battery charging data of the battery (e.g., battery 71) over time. In embodiments, the power management server 60 monitors the battery performance of the battery (e.g., battery 71) for deviations in performance over time. In aspects, the battery monitoring module 82 of the power management server 60 implements substep 302 b. In embodiments, the power management server 60 accesses historic battery charging data and compares real-time battery charging data to the historic battery charging data to determine a change in battery performance over time. Existing battery performance monitoring techniques may be utilized in the implementation of subset 302 b.

At substep 302 c, the power management server 60 sends an alert based on the monitoring of substep 302 b. In aspects, the power management server 60 sends an alert to one or more in-use devices 62 of the user indicating a degradation in the performance of the battery (e.g., battery 71) when the power management server 60 determines the battery performance has degraded below a predetermined threshold value based on the monitoring of substep 302 b. The term in-use device as used herein refers to a user device that is currently being utilized by a user, either directly (e.g., data is input/accessed) or indirectly (e.g., device is worn or carried by the user). Further details regarding the identification of in-use devices are set forth below with respect to step 305 of FIG. 3. In one example, if a charge of the battery 71 decreases more than 10% on more than 2 instances, then the power management server 60 triggers an alert regarding the identified level of degradation of the battery 71. In one example, the alert is in the form of a text-based message indicating that the battery 71 is failing. In aspects, the battery monitoring module 82 of the power management server 60 implements substep 302 c.

At step 303, the power management server 60 monitors battery charge levels of registered user devices via the network 55. In embodiments, the battery monitoring module 82 implements step 303. In implementations, the power management server 60 monitors battery charge levels by obtaining battery charge data directly from a user device (e.g., in-use device 62), or obtains battery charge data from existing battery management software of the user device (e.g., battery management software of the power module 72 of in-use device 62). In aspects, the power management server 60 utilizes existing battery monitoring techniques in the implementation of step 303. In embodiments, the battery monitoring module 82 of the power management server 60 implements steps 304.

At step 304, the power management server 60 determines that the battery charge level of a registered user device (e.g., in-use device 62) is below a predetermined threshold value, and the user device is a low-power device. In one example, if the battery charge level of the headphones 64 is at 10% of its full charge, the power management server 60 determines that headphones 64 are a low-power device. In aspects, the predetermined threshold value is set by administrators, obtained by third parties, or obtained from user input (e.g., user registration information). In embodiments, the battery monitoring module 82 implements steps 304.

At step 305, the power management server 60 identifies one or more registered user devices that are currently in use by a registered user as in-use devices (e.g., in-use devices 62). As noted previously, the term in-use device as used herein refers to a user device that is currently being utilized by a user, either directly (e.g., data is input/accessed) or indirectly (e.g., device is worn or carried by the user). In one example, a user is determined to be using a registered user device when the device is being carried by the person (e.g., a wearable device or smartphone), or when the user is directly utilizing the device such as through interacting with a GUI of the device (e.g., GUI 70 of in-use device 62). In embodiments, only registered user devices enabled to communicate notifications or alerts to a user are considered by the power management server 60 as in-use devices. In one example, the power management server 60 utilizes user device profiles in the user database 81 to determine which user devices contain GUIs (e.g., GUI 70 of in-use device 62), and designates only those user devices with GUIs as being in-use devices in accordance with step 305.

In implementations, the power management server 60 determines if a registered user device is currently in use utilizing a number of methods. In implementations, the power management server 60 determines which registered user devices are currently in use by: pinging the user device, obtaining device metadata such as last usage timestamp data, determining if the device is locked or unlocked, and/or using device sensors (e.g., accelerometers) to detect movement of the devices. In embodiments, if multiple registered user devices are in use at the same time, the power management server 60 identifies all or a subset of the user devices as in-use devices. In aspects, the power management server 60 identifies in-use device's based on prioritization of the user devices, such as through the use of prioritization information in the user database 81 indicating an order of priority for the user's various devices.

At step 306, the power management server 60 sends a notification or alert to one or more in-use devices identified at step 305, including information regarding the low-power device and information regarding the battery status. In one example, the power management server 60 determines at step 304 that the battery charge level of the headphones 64 of FIG. 2 has fallen below a predetermined threshold value, and then send an alert to the in-use device 62 indicating that the battery of headphones 64 is low on power in accordance with step 306. In another example, the power management server 60 determines that a first in-use device has a low battery level at step 304, and then send an alert to the first in-use device and a second in-use device in accordance with step 306, indicating that the first in-use device is low on power.

Optionally, at step 306, the power management server 60 sends one or more battery management options to one or more in-use devices with the notification or alert. In implementations, the power management server 60 sends user-selectable battery management options including options to: shut down the low-power device; disable some features of the low-power device to save power, initiate device-specific (e.g., proprietary) battery saving functions of the low-power device, hibernate the low-power device, initiate a sleep mode of the low-power device, or the like. In embodiments, the notification module 83 of the power management server implements step 306.

If step 306 is initiated, at step 307 the power management server 60 receives a selection of one or more battery management options from a user (e.g., via GUI 70 of in-use device 62). In one example, a user of in-use device 62 selects to power off headphones 64 based on an alert indicated that the headphones 64 are low on power. In embodiments, the notification module 83 of the power management server 60 receives the selection from a user in accordance with step 307.

At step 308, the power management server 60 sends battery management instructions to the low-power device identified at step 304 based on the received selection of one or more battery management options at step 307. In one example, the power management server 60 sends instructions to the headphones 64 to power off based on the receipt of a battery management option from the in-use device 62 to power off the headphones 64. In embodiments, the battery monitoring module 82 is in communication with the notification module 83 and implements step 308 based on the receipt of the battery management option selection by the notification module 83.

At step 309, the power management server 60 determines if the instructions of step 308 have been successfully implemented by the low-power device. In embodiments, the power management server 60 determines if the instructions have been successfully implemented based on a notification received from the low-power device indicating that the instructions were or were not successfully implemented. In one example, in response to receiving instructions from the power management server 60 to go into a sleep mode, the headphones 64 send a notice to the power management server 60 that the headphones 64 have been successfully transitioned to a sleep mode.

At step 310, the power management server 60 sends a notification to the user based on the determination of step 309. In embodiments, the power management server 60 sends a notification to the one or more in-use devices identified at step 305. In one example, the power management server 60 sends a notification to a user via one or more in-use devices 62 that the headphones 64 were successfully transitioned to a sleep mode. In an alternative example, the power management server 60 sends a notification to a user via one or more in-use device 62 that the headphones 64 were not successfully transitioned to a sleep mode. In aspects, the notification module 83 implements step 310.

FIG. 4 shows a flow diagram illustrating steps of the method of FIG. 3 in accordance with aspects of the invention, and is described with reference to elements shown in FIG. 2. For ease of reference, the power management server 60 is referred to as simply the “server” in FIG. 4.

With reference to FIG. 4, at step 400 the power management server 60 receives device information and saves it in a user database (e.g., user database 81), in accordance with step 300 of FIG. 3. At step 401, the power management server 60 determines if one or more registered user devices have associated battery management software loaded therein in accordance with step 301 of FIG. 3. If the power management server 60 determines that a user device (e.g., in-use device 62) does include battery management software, then at step 402, the power management server 60 monitors the user device for battery charge levels in accordance with step 303 of FIG. 3. If the power management server 60 determines that the user device is a lower battery device due to the battery level being below a predetermined threshold value at step 403 (in accordance with step 304 of FIG. 3), then at step 404 the power management server 60 identifies one or more in-use devices, in accordance with step 305 of FIG. 3. Conversely, if the power management server 60 determines that the battery level is not below a predetermined threshold value at step 403, then the power management server 60 will continue monitoring the battery charge of the user device in accordance with step 402. In aspects, the monitoring of step 402 is performed on a continuous or periodic basis.

Still referencing FIG. 4, in embodiments, if the power management server 60 identifies that the low battery device is the same as the in-use device at step 405, then the power management server 60 identifies at least one additional in-use device (secondary in-use device) at step 406. At step 407, if the in-use device is not the same as the low battery device, then the power management server 60 determines if the low battery device allows for remote battery management of the low battery device. Similarly, if a secondary in-use device is identified at step 406, then the power management server 60 determines at step 407 if the low battery in-use device allows for remote battery management of the low battery in-use device. In aspects, step 407 conducted in accordance with step 301 of FIG. 3 (i.e., determining whether the in-use or secondary in-use device has battery management software). In aspects, the power management server 60 accesses user device data on the user database 81 to determine if the registered in-use device or secondary in-use device includes dedicated remote battery management functionality.

At step 408, if the power management server 60 determines that the in-use device or the secondary in-use device does not include remote battery management functions, then the power management server 60 sends an alert to the in-use device and/or secondary in-use device to alert the user regarding the low battery device. In embodiments, the power management server 60 sends an alert to the secondary in-use device alerting the user that the in-use device has a low battery. In embodiments, the power management server 60 sends an alert to all in-use devices determined at step 404, or to a predetermined select subgroup of the in-use devices. In aspects, step 408 of FIG. 4 is performed in accordance with step 306 of FIG. 3.

At step 409, if the power management server 60 determines that the in-use device or the secondary in-use device does include remote battery management functions, the power management server 60 sends an alert with battery management instructions to the low battery device identified at step 403, in accordance with step 308 of FIG. 3. At step 410, the low battery device executes the battery management instructions, such as powering off the low battery device. In aspects, the low battery device sends an alert back to the power management server 60 indicating that the instructions were or were not implemented. At step 411 the power management server 60 determines if the instructions sent at step 409 were executed successfully, in accordance with step 309 of FIG. 3. If the instructions were successfully executed, then at step 412 the power management server 60 sends confirmation to the in-use device and/or the secondary in-use device to inform the user that the instructions were successfully executed. Alternatively, if the power management server 60 determines that the instructions were not successfully executed at step 411, then at step 413, the power management server 60 sends an error alert to the in-use device and/or secondary in-use device.

If the power management server 60 determines that a user device (e.g., in-use device 62) does not include associated battery management software for the device at step 401, then at step 414, the power management server 60 tests battery performance in accordance with step 302 of FIG. 3. At step 415, the power management server 60 monitors the user device and gathers battery performance data and sends an alert to the user based on the battery performance data at step 416. In implementations, steps 414-416 are implemented in accordance with steps 302 a-302 c of FIG. 3. In embodiments, the power management server 60 sends an alert at step 416 to one or more identified in-use devices of the user (e.g., in-use device 62) based on battery performance data gathered at step 415.

FIG. 5 shows a flowchart of a cognitive battery management method in accordance with aspects of the invention. Steps of the method of FIG. 5 may be performed in the environment illustrated in FIG. 2, and are described with reference to elements shown in FIG. 2.

At step 500, the power management server 60 determines that a user device (e.g., off-line device 63 of FIG. 2) is in an off-line or on-line mode. In embodiments, step 500 is implemented concurrent with one or more steps of FIG. 3. For example, step 500 may be implemented prior to step 303 of FIG. 3. The term off-line mode as used herein refers to a reduced function mode of a registered user device (e.g., off-line device 63) that results in a situation wherein battery management software of the user device or battery system components (e.g., microprocessor) of the registered user device are not accessible by the power management server 60 (e.g., via the network 55) for monitoring. In other words, when a device is off-line, the power management server 60 is unable to obtain battery status data of the off-line user device. Examples include when a device is powered off, in a sleep mode, in a hibernation mode, or the like. Conversely, the term on-line mode as used herein refers to an active mode wherein battery management software of a registered user device or battery system components of the registered user device are accessible by the power management server 60 (e.g., via the network 55) for monitoring. In embodiments, step 500 is implemented by the battery monitoring module 82 of the power management server 60.

At step 501, the power management server 60 causes an off-line device (e.g., off-line device 63) to change from an off-line mode detected at step 500 to an on-line mode, based on a predetermined wake-up schedule. In embodiments, predetermined wake-up schedules are saved in individual user device profiles on the user database 81, wherein the wake-up schedules define a time period between scheduled wake-up sessions. The term wake-up session refers to a time for initiating a change from an off-line status to an on-line status to “wake” an off-line user device (e.g., off-line device 63). In one example, the power management server 60 determines at step 500 that a smartwatch 65 if off-line (in a sleep mode) and, based on a predefined schedule indicated that the battery status of the smartwatch 65 should be checked every 5 hours, sends instructions to the smartwatch 65 to initiate a wake-up session, wherein the instructions cause the smartwatch 65 to change from the off-line mode to an on-line mode. In embodiments, step 501 is implemented by the battery monitoring module 83 of the power management server 60.

At step 502, the power management server 60 receives battery status data from the on-line user device. In aspects, battery status data includes battery performance data and battery charge level data. In embodiments, step 502 is implemented as part of steps 302 and/or 304 of FIG. 3. A variety of existing battery monitoring methods may be utilized in the implementation of step 502. In aspects, the power management server 60 receives battery status data from dedicated battery management software on a user device (e.g., off-line device 63), via the network 55. In embodiments, the power management server 60 receives battery status data directly from battery system components (e.g., microprocessor) of a user device, via the network 55. In aspects, battery status data is saved in a database of the power management server 60, or a remote database.

At step 503, the power management server 60 sends instructions to the on-line user device to cause the device to revert back to its previous off-line mode. In aspects, the battery monitoring module 82 of the power management server 60 implements step 503. In one example, the power management server 60 sends instructions to the smartwatch 65 to revert from a current on-line mode to the previous off-line mode, which was a sleep mode.

At step 504, the power management server 60 compares battery status data received at step 502 to historic battery status data to determine a difference in battery status. In embodiments, the battery monitoring module 82 of the power management server 60 implements step 504. In aspects for step 504, the power management server 60 accesses historic battery status data save on the power management server 60 to compare a current battery status received at step 502 with the battery status data from a previous iteration of steps 500-505.

Optionally, at step 505, the power management server 60 adjusts the predetermined wake-up time utilized at step 501 based on the difference in battery status determined at step 504. In embodiments, the delta in battery status determined at step 504 is compared to threshold values to determine if the wake-up time should be adjusted. In a first example, if a delta between battery status for the smartwatch 65 is less than 10% (when the device always off), then the power management server 60 increases the wake-up time (i.e., period between wake-up sessions) for the smartwatch 65 by 20%. In another example, the power management server 60 determines that a battery of a controller 66 loses a charge at a rate of 5% per day when off-line, and determines that there is no need to obtain battery status data from the controller 66 on a daily basis because doing so would drain more power from the battery. Accordingly, the power management server 60 in this example checks the battery status data of the controller 66 every 2 or 3 days, resulting in an accumulation of battery status data over time without a significant impact on the battery life of the controller 66. In other scenarios, if a user device loses power very quickly when off-line, waiting 24 hours to obtain battery status data may be too late. In such cases the power management server 60 progressively reduces the wake-up time in a device schedule to adjust to the battery level of the device.

Steps 500-505 may be repeated, resulting in incremental adjustment of the predetermined wake-up time for individual user devices over time. Advantageously, as the batteries of user devices age and performance degrades over time, the method of FIG. 5 enables cognitive adjustment to the battery management methods utilized by the power management server 60. In other words, since the process of FIG. 5 is iterative, the power management server 60 will adjust the wake-up time of a user device progressively with the battery. In fact, batteries eventually decrease their autonomy and the embodiments of the invention are designed to automatically adjust to the current battery autonomy. This ensures that each device profile remains unique, with different wake-up schedules for each device base on respective battery life and performance.

FIG. 6 shows a flow diagram illustrating exemplary cognitive battery management steps in accordance with aspects of the invention. Steps of FIG. 6 may be performed in accordance with FIG. 5, and are described with reference to elements shown in FIG. 2.

At step 600, the power management server 60 determines if a registered user device is in an on-line state or an off-line state, in accordance with step 500 of FIG. 5. If the power management server 60 determines that the user device at issue is on-line, then at step 601, the power management server 60 simply monitors the device battery levels in accordance with step 303 of FIG. 3. However, if the power management server 60 determines that the user device at issue is off-line, then at step 602 the power management server 60 determines a wake-up time associated with the user device. In aspects, the wake-up time is saved in the user device profile in the user database 81 or a remote database (not shown). In one example, the wake-up time for a device is based on a schedule of wake-up events every 24 hours. At step 603, the power management sever 60 sends instructions to the user device (e.g., off-line device 63) at the scheduled wake-up time to switch the user device from the off-line state to an on-line state, in accordance with step 501 of FIG. 5. At step 604, the power management server 60 obtains battery status data from the user device (e.g., battery charge data, battery performance data, etc.) in accordance with step 502 of FIG. 5 and/or step 303 of FIG. 3. At step 605, the power management server 60 sends instructions to the user device at issue to revert the device to the previous off-line state, in accordance with step 503 of FIG. 5. In one example, the power management server 60 sends instructions to the user device to revert back to a hibernation state.

With continued reference to FIG. 6, at step 606, the power management server 60 determines if the battery status of the device (e.g., battery charge level) has changed more than 50% while the user device was off-line. If the power management server 60 determines that the battery status of the device changed more than 50% while the device was off-line, then at step 607 the power management server 60 decreases the wake-up time by 20% in accordance with step 505 of FIG. 5. Conversely, if that battery status of the device has not changed more than 50% while the device was off-line, then the power management server 60 determines if the battery status has changed less than 10% while the device was off at step 608. If the power management server 60 determines that the battery status of the device has changed less than 10% with the device off, then the power management server 60 increases the wake-up time by 20% in accordance with step 505 of FIG. 5. Accordingly, the next time the power management server 60 determines the device wake-up time at step 602, it will be increased by 20%. Conversely, if the power management server 60 determines that the battery status has changed more than 10%, but less than 50%, then wake-up time for the device will remain unchanged, and the cycle of FIG. 6 will repeat. Thus, it should be understood that embodiments of the invention incrementally adjust wake-up times for battery monitoring of a device as a battery of the device degrades over time.
